Production of beams of multi-charged iron ions 56Fe with energy 0.64 - 7.92 MeV for irradiation of construction materials

摘要

n the paper, a possibility of multiply charged 56Fe ions beams formation for imitation irradiation of reactor materials with using the IAP NASU accelerator mass spectrometer is considered. There are iron ions of various charge states (up to 56Fe8+) in obtained mass spectra. Despite of the ion current decreases with increasing charge state, multicharged ions can be used to irradiate specimens when larger ion energy is required. It is shown defect formation rate for 56Fe sample irradiated by 56Fe2+ ions with energy 2.52 MeV is 2.7⋅10-3 dpa/s.
